Sandu Popescu is a Professor of Physics at the H. H. Wills Physics Laboratory at the University of Bristol, and a member of the Bristol Quantum Information and Computation Group. He has made numerous contributions to quantum theory, ranging from the very fundamental, to the design of practical experiments (such as the first teleportation experiment), to patentable commercial applications. His investigations into the nature of quantum behavior, with particular focus on quantum non-locality, led him to discover some of the central concepts in the emerging area of quantum information and computation. He is a past recipient of the Adams Prize (Cambridge), and the Clifford Patterson Prize of the Royal Society (UK).
